Lifestyle inflation quietly erases income growth. Earning 3% raises but spending them all leaves real wealth flat. Saving 50% of each raise while maintaining current lifestyle compounds quickly. A 60,000 income with 3% raises saving half of each raise for 20 years accumulates roughly 42,000 extra compared to full lifestyle inflation. The number grows with discipline and time.
Run it with sensible defaults
Using current annual income of 60,000, annual raise of 3%, share of raise saved of 50%, years of 20, the calculation works out to 42,030.73. Nudge the inputs toward your own situation and the output recalculates instantly. The defaults are meant as a starting point, not a recommendation.
The levers in this calculation
The inputs — Current Annual Income, Annual Raise %, Share of Raise Saved, Years, and Investment Return — do not pull with equal force. Two inputs usually tip the answer one way or the other. Identify which ones matter most by flipping each value past a round threshold and watching whether the winning option changes.
How the math works
Year-by-year: raise amount = prior income × raise rate. Saved portion invested from that year forward. Sum of FVs across years. The working is transparent — you can verify every step yourself in the formula section below. No black box, no opaque "proprietary model".
The annual review habit
Plug new numbers in every year. Income changes, expenses shift, markets move. A plan that isn't revisited quietly drifts out of date. This tool is cheap to re-run — so re-run it.
What this doesn't capture
Real plans get re-run against new information every year or two. The result here is a reasonable direction, not a destination. Treat it as a starting point for thinking, not a commitment to a specific future.
